Threonine344/Serine347 (T344/S347) is a major phosphorylation site of the NK1 receptor. The pT344/pS347-NK1 antibody detects phosphorylation in response to high-efficacy agonists. T344/S347 phosphorylation is a key regulator of NK1 desensitization, β-arrestin recruitment and internalization.

Figure 1. Agonist-induced Threonine344/Serine347 phosphorylation of NK1 Receptor. Upper panel, HEK293 cells stably expressing the NK1-Receptor (NK1) were either not exposed or exposed to 1 µM of specific NK1-Receptor agonist Substance P for 30 minutes. Cells were lysed and immunoblotted with the anti-pT344/pS347-NK1 antibody (7TM0360A) at a dilution of 1:1000. Lower panel, blot was stripped and reprobed with the phosphorylation-independent anti-NK1 antibody (7TM0360N) at a dilution of 1:1000 to confirm equal loading of the gel.
